The above way is pretty easy to do too, but don't forget you can always just put the frozen mouse in the fridge and let it thaw overnight, then all you have to do is put it under the heat lamp for a few minutes and you got yourself a yummy mouse...takes half the time if you can remember to put it in the fridge the day before.
Theres so many ways to do it, do whatever creeps u out the least, haha
